Spcciticationforniing' part of Letters Patent No. 19,! 79, dated January 26, 1858,

-Subsoil Cultivating-Plow; and Ido hereby declare that the followinglr is a full and exact description thereof', reference being had to thel accompanying drawings,l making part of this specitication- Figure 1 being a side elevationof the plow; Fig. 2, a horizontalsection,thereof` in the plane indicated by the line :n x, Fig'. 1;l Fig. 3, rear view of a portion of the standard G, which supports the handles', showing the methodof adjusting the handles.

Like letters designate corresponding parts in all the h'gures.

-To construct the stock of the plow I take three pieces of a. bar of iron, each of suitable length, and bend them respectively into the shapes shown in Fig. 1,-the hind bar, F, being straight, ,and the two forward bars, G H, being curved, substantially as shown'. The upper ends aresecured to the under side of the beam A, respectively by bolts g h i, in the positions The two rear bars, F G, are united by a. rivet near their lower ends, which are sharpened in the manner shown. The lower end of the front bar, H, terminates at some distance above the ends of the other two bars, and, being blunt, serves as a shoulder for the rear end of the pbint L to bear against; A rivet passes through all' three ofthe bars nearthe lower end of the front bar, H.

The point L, which may be of any desirable form, is laid upon the middle bar, G, its rear end bearing against the end of the bar H, as above specified. A bolt, f, passes through it and the bars F G, whereby it is secured tothe stock.'

The colter I is constructed and arranged in a peculiar manner. It ismade ot' ordinary size at the upper end, and `the lower end divides into threebranches, a l) c, substantially as represented in Fig. 1. The fore branch, c, curves forward and has a. pointed end, which enters a. notch -in the top of the point L, thereby holding said point in its proper place and steadyingv it. The middle branch, b, which is about in the -line of the shank of the coller, enters notchesboth in the rear end of the point L and 'the lower end of the bar H, and rests therein. This serves especially to prevent any side movement of the point, besides giving an additional strength as a brace. The hind branch, c, extends backward-to and bears against the bar H, which may have a notch for the reception of the extremity of the branch. Said branch serves to strengthen the colter at a..

point where it is most liable to give way, and forms abracng and steadying connection between the parts. The shank of the colter extends through a wide mortise in the beam A, in which itis secured and adjusted in the right position by wedges m m, driven down beside each edge.

Iprovde an improved mode of adjusting the handles B B to the desired height in the following manner: The front endsof the handles are secured against the sides ofthe beam by a pivot, c, which allows them to turn thereon. A sipporting standard, C, extending upward from the rear end ofthe beam, is curved a little at the top, so as to heconcentric withthe pivot e. Said standard is made sufficiently thick transversely to admit two rows of hotles, r o', side by side, as shown in Fig. 3. The stretcher-bar M, which connects the handles, embraces this standard, and has two holes, corresponding with two adjacent holes in the standard, through which bolts t t. pass, and thus hold the handles at the given height. This mode ot' securing by double bolts and holes prevents the side-wresting to which the handles are otherwise liable.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the tri ple-branched colter I, bars Ff G H, and point L, constructed and arranged as herein specified.

JOSEPH BANKS.
